British auto journalist Jonny Smith owns the Flux Capacitor, an old Enfield 8000 electric city car that he converted into one of the quickest EVs out there.

It’s unclear where this car ranks as the quickest EV in the world, because even though Ars Technica says it is, it doesn’t cite a specific records source such as the Guinness Book of World Records (a quick search turned up nothing related to the Flux Capacitor).

Regardless of where it stands, the Flux Capacitor isn’t slow – it ran the quarter-mile in 9.87 seconds on July 16.

This street-legal EV uses a 144-cell lithium-ion battery pack that’s bolstered by another 44 cells located in the trunk. That bumps voltage from 370 to 400, while a lower gear differential helps with acceleration off the line as well. The car originally had an array of 12-volt batteries and an eight horsepower electric motor.

“The combination of big voltage, amps, and phenomenal grip gave us early ten-second quarter miles, and when we braved the rpm limit of the motors, we managed a nine [-second run],” Smith said to Ars Technica. “Despite all of this power and speed, the little Enfield still felt smooth, stable, and happy, which is unbelievable given that it was designed to do 40 miles an hour.”

“I love this car for its sheer British engineering eccentricity, and I am glad to be bringing back a forgotten EV – thrusting it into the limelight of today,” Smith said. “The R&D help from Olly Young at Current Racing has been invaluable to our success; Britain’s taking back the amp kicking.”

Off track, the Flux Capacitor has a range of around 50 miles, compared to the original range of 30 miles.
